If I am to understand your intentions correctly, I've cast my vote. I've used all three brands, and currently have some of them all in my possession.
I think that the best "work knife" is dependent on the work to be done. My requirements for my daily-carry slipjoint are pretty lenient, usually opening packages, removing an occasional splinter, cutting a piece of string or rope.
For food-prep, boxcutting, wirestripping, etc I use a tool better tailored for the job at hand.
All three of the brands you've listed make fine slipjoints that are more than adequate for my needs. That being said, like most people I have a favorite. I'm certainly curious to see how this poll turns out, and thanks for taking the time to put it up.
Case cause I could never really work a knife that cost over 75 dollars.
If we change the intent to "value" then it is a bit of a different question and we would need to include the Opinel; which is at least 1/6th as good as Queen or GEC knife at 1/6th the price.
But, the question was not intended to be respective to what you might lose; it was which company do you think makes the best work knife.
